This is a house for a couple and a small son in Sakai City, Osaka Prefecture, Japan. We designed a large house with a square plan and designed four small houses from each vertex. The gap between small houses becomes a crossroad. The small houses are designed to be alone and the crossroad is designed to stay with the family. Residents can live in and out of small houses and a large house. The windows of small houses are connected to the crossroad, and the windows of the large house are connected to the garden, gentle hills, trees of the forest, the sky and the clouds.
